Hi,
During investigation of some issues during hotspoting we were moving some
regions to different region servers. However, now I see that balancer is
not affecting those regions anymore - they 'stick' to those servers. Is
there a way to force rebalancing in case like this?
Thanks!
Hi Dejan,
Most probably because the cluster is balanced enough?
You can run the balancer from the shell and look in the logs to see what's
the outcome.
Simply type "hbase shell" and then "balancer". It will also return the
state of the balancer (true for active, false of passive).

Hi Jean-Marc,
Ok, that's what I thought too, just wasn't sure as I didn't see any error
anywhere, neither something happening when I run balancer, so it's good
then :)
Thanks a lot!

Did you alter configuration defaults (Defaults write data to /tmp dir so a
restart could cause loss if OS clears tmp).
Shutdown all HBase-related services then restart. If still does not log,
post link to complete log.

In the upcoming 1.1.0 release, the following would make balancer state
inspection more user-friendly:
HBASE-13222 Provide means of non-destructive balancer inspection

The HBase Team is pleased to announce the immediate release of HBase 1.0.1.
Download it from your favorite Apache mirror [1] or maven repository.
HBase 1.0.1 is the next “patch” release in the 1.0.x release line and
supersedes 1.0.0.
According to the HBase’s semantic version guide (See [2]), the r
Hi all,
Is it possible to specify the output HDFS directory for HBase snapshot?
It could be very helpful to keep snapshots sorted according to a date.
Thank you.

Akmal Abbasov
on export you can specify any path
$ hbase org.apache.hadoop.hbase.snapshot.ExportSnapshot -snapshot
MySnapshot -copy-to hdfs://MY_SERVER:MY_PORT/MY_LOCATION
so you can do:
$ hbase org.apache.hadoop.hbase.snapshot.ExportSnapshot -snapshot
MySnapshot -copy-to hdfs://localhost/backup/january-2015

Hi Matteo,
Thank you, for a quick reply.
In this case, after exporting a snapshot to the location I want in my local
machine,
can I delete the same snapshot from the default location,
/hbase/.hbase-snapshot ?
Thank you.
Regards,
Akmal Abbasov

Hello,
We'v been fighting some ingestion perf issues on hbase and I have
been looking at the write path in particular. Trying to optimize on write
path currently.
We have around 40 column qualifiers (under single CF) for each row. So I
understand that each put(row) written into hbase would
.. I'd like to add that we have a very fat rowkey.
- Thanks.

Hi Gautam,
Your reasoning is correct and that will improve the write performance,
specially if you always need to write all the qualifiers in a row (sort of
a rigid schema). However you should consider to use qualifiers at some
extent if the read pattern might include some conditional search, e.g.
Thanks for the quick response!
Our read path is fairly straightforward and very deterministic. We always
push down predicates at the rowkey level and read the row's full payload (
never do projection/filtering over CQs ). So.. I could, in theory, expect
a gain as much as the current overhead of
